When is it safe to surface after a dive using EANx?

• A. As soon as the diver feels ready
• B. After completing all scheduled stops and ensuring no symptoms are present
• C. Credit on dive logs allows immediate surfacing
• D. Whenever the dive computer indicates it is safe

Answer: (B)

It is important to ensure the safety of divers during ascent and surfacing after a dive, particularly when using Enriched Air Nitrox (EANx). The correct response emphasizes the necessity of completing all scheduled safety stops and ensuring that no symptoms of decompression sickness are present before surfacing. Safety stops are critical as they allow for gradual ascent, which helps to minimize the risk of nitrogen bubbles forming in the body—a key concern for divers, especially after longer or deeper dives. By completing all planned stops, divers can reduce their risk of potential decompression sickness. Additionally, being aware of and monitoring for symptoms ensures that divers are attentive to their bodies’ responses to the dive’s conditions. The other options highlight misconceptions or oversights related to dive safety. Feeling ready to surface does not account for physiological factors that could necessitate a more cautious approach. Similarly, relying on credit in dive logs or solely on dive computer indications might overlook critical safety protocols. Hence, the emphasis on scheduled stops and symptom monitoring is vital for a safe return to the surface after a dive.
